What about a single button to turn MCAS off and return to trim to a neutral position? Or a setting where the pilot is telling the system to ignore the sensor input.
Maybe a bit like a self driving car planes will eventually have a system where they can use visual markers as a check on what sensors are reporting.

- javagram 8y agoIndeed there are many ways to design this better. The 737 max was designed to not be any different to fly than previous 737s, so adding a button to disable this system was not allowed as I understand it. As these two tragic accidents have made clear that specification was pretty wrongheaded...
- fgonzag 8y agoSeriously, a MCAS indicator light (if MCAS is actively issuing commands), a big red button below it called "Disable MCAS" , and a MCAS disabled light (so pilots actually remember when it is disabled) should be more than enough to prevent this. Besides adding the AoA disagree light AND having MCAS use a triple AoA sensor vote to determine the AoA angle.
